To all whom -iimay concern.:

Be it known that. I, JAMES A. HERRICK, a citizen of the United States. residing in the city of New York, county of New York. and State of New York. have invented certain Improvements in Gas-Producers.

'This invention is an improved gas produeer designed particularly for burning small anthracite coal to produce gas for plants requiring a limited amountA of power, but. also adapted for producing large volumes of gas either from anthracite coal, or, with slight-changes, from-bituminous coal.

ln the usual gas producers. of the suetion type .for burning small anthracite coal. 'the' following serious faults are encountered which itisthe objectl of my improvements to correct ln prior producers of this type theconstructions are complex. costly and dillioult to operate: leakage of gas and nneontrolled ingress of air are common: viewing` poking and prevent-ing einders from building up from the sides are diz'licult so that. producers cannot. be run continuously: combustion is not regular owing to imperfeety means for supplying and distributing air and steam: steam andheated air are supplied at considerable cost. both for appa ratas and operation. and the produc-er tops are heated so that they are frequently warped and destroyed. i

The characteristic features of my improvements will appear from the following description of the accompanying drawings in illustration thereof.

ln the drawings, Figure 1 is a vertical sectional view of a producer embodying my improvements: Fig. 2 is a horizontal sectional view thereof; Fig. 3 is a vertical scctional view of thelower part-ot the construt-tion taken at right angles to the view shown in Fig. l.

.\s shown in the drawings. the base A contains the water seal and ash basins separated by the ridge A: which terminates in an angle. the intersecting slopes forming the ridge .being inclined so as to throw outward The parallel walls A". forming sides for the basins. carry the lS'pecicatien of Letters Patent. 'l P'atlenvteid Application filed July 24, 1908. Serial -No. 445,070.

circular producer body B, the base having below lthe general level thereof the. piers for support-ing the base and the circular channels A communicating with the basins from which they receive water to seal the lower part of the body. Extending across the body above the ridge and parallel there- Y to is the blast box C which is formed in two similar parts separated on a longitudinal'- vertleal plane and connected together b vbolts C and Cipassing through the tops and bottoms thereof. The two `parts of the blast box have the inclined tops @l which, join together to form a sharp ridge.. the -verft tical walls C containing the apertures C51.

immediately beneath the parts C". the olitwardly inclined walls immediately be--i neath the walls C4, the vertical wallsl C7 eon-' taining the apertures Cs immediately lieneath the walls Cr'. and the inwardly inclined walls C coming together under the` ridge and containing the apertures C. These apertures are placed and prol'iortioned so that they deliver and distribute the blastufl in the most eliieaeions manner.

The producer body is provided with a manhole B in line with the blast box, by which access is had to its interior through .l

the rear end. and with capped poke holes B2, ln' wlneh access is had to the regions above and on either side of the blast box, to break up elinkers tending toform there. A hollow ring D, formino' a closed channel havst ir the fuel. the poker being withdrawn from the balls and the latter turned to close the holes. Further openings D. passing through the ring at suitable intervals, provide means for viewing. These openings are D in its top, forms the A funnel D2 is' Y the caps D" for c osing them, the caps being thrown back and a tube D itted to a tube D12 for the urpose of making an examination. By tiese arrangements stirring and viewing can be e`ectedwithout material escape of as or ingress of air, which are very obectionable. The body is covered by a top having a channel formed by the yianges or walls E and E2 thereon, the lat- Y ter also forming the wall of a fuel passage through the top. A pipe E3 admits water to this channel and a .pipe E* carries the overiiow therefrom into the channel D.

A hopper F is connected to the top by a hinge F', has the lat rally extending base ll`2 A adapted to rest on he flange E2, and the fiange or apron F3 depending into-the channel, a hook Es engaging the hopper to its seat on the top. A cone valve F4 closes' the ssage from the hopper through the top, ing held up against its seat by a weighted lever F connected thereto and supported by 26 the -fulcrum 1?" on the hopper. A tightly fittinfr hood F7 covers the hopper; in charging, the hood being removed by a. lever F' connected therewith and fulcrumed on a pivoted post F carried by the hopper. The ood may detached from the hopper and A placed over the ange E2,for greater convenience of access to the interior and viewing through the capped a erture F, the hopper having been turned ackward on its hinge'.

A conduit G extends from the ring D of the top to the inlet end of the blast box C in the bottom of the body, a valve G controlling the admission of air to the top of H', leads from the interior of the upper and outer part of the ring D into the outlet from the conduit G to the blast box C, and creates suction through the conduit by dischar in through' its outlet steam or vapor evo veA from the water in the channel through the action of the heatin the top of they body.

The gas take off pipe I, connected with the interior of the top of the body by the passage D through the ring, is inclosed within the conduit G to the level of the outlet therefrom so that air flowing through this conduit on its way to the blast box 'is heated by the gas liowing in the pi e and the gas is cooled, the mechanism provi ing an economic temperature intcrchanger. It will be understood that flow through the pipe I will be facilitated enerally by the suction of an engine or ot er apparatus (not shown) to' which the gas is supplied, and the How of air through the conduit G facilitated thereby.

A purge pipe J is connected to the pipe-I 'exterior to the conduit G, and is provlded the conduit. A pipe H, containing a valve with the -valved pipe J for testing the gas and the sealed cap J" for opening the top, B5y the pipe being used when lighting the fires, for carrying off waste gases, as a safet blow-off, and for obtaining gas to vbe teste The foregoing construction is practically leak proof and is satisfactorily cooled where the high temperatures are usually destructive, since the sealing basins are of unusual depth, the bottom of the body is entirely surrounded by water, the top of the body is formed by a hollow ring containing water, the parts of the top or cover in contact with the hot gases are water cooled, the connection of the hopper with the top is sealed and tight, and the passage through the hopper is securely closed by the tightly fitting valve and hood. The interior of the body can be poked and the fire examined very readily through the poke holes and viewing apertures, without egress of gas or ingress of air. The water that cools the top of the producer in slo doing absorbs heat bywhich vapor is produced that is utilized in effecting the desired combustion. The air to be used to Ycarry on combustion is given a desired increase in temperature by absorbing heat from the gaswhich it is desired to cool, and this air is distributed so that a proper portion thereof reaches all parts of the fuel. The mechanism is simple, inexpensive and not liable to get out of order. The ashes are thrown outward by the ridge into the basins which have their deepest parts beneath the wall of the body so that the ashes can be withdrawn readily.
